Description

本発明は、主として建築物内の間仕切り壁として使用される断熱耐火パネルに関するものである。   The present invention relates to a heat insulating and fireproof panel mainly used as a partition wall in a building.

特許文献１（特公平８−１９７５７号公報）には、金属板で形成される表裏の外皮間に断熱材を充填したサンドイッチ構造の断熱耐火パネルが開示されており、隣接パネルとの接合構造として、一方の端縁（パネル幅方向の端部）に嵌合突部を形成し、他方に嵌合凹部を形成し、パネルの嵌合連結によって所定の壁面を構成するようにしている。   Patent Document 1 (Japanese Patent Publication No. 8-19757) discloses a heat insulating fire-resistant panel having a sandwich structure in which a heat insulating material is filled between outer and outer skins formed of a metal plate. A fitting protrusion is formed on one end edge (an end in the panel width direction), and a fitting recess is formed on the other, so that a predetermined wall surface is configured by fitting connection of the panels.

特に特許文献１記載のパネルにおいては、嵌合突部と嵌合凹部にパネル連結力を高めるために、嵌合突部の外側面と嵌合凹部の内側面に、鉤状に形成した係止部を設けている。   In particular, in the panel described in Patent Document 1, in order to increase the panel connecting force between the fitting protrusion and the fitting recess, the engagement formed on the outer side surface of the fitting protrusion and the inner side surface of the fitting recess is a hook shape. Is provided.

また特許文献２（特許２８７５７４３号公報）には、外皮間に充填する断熱材として、パネルの幅方向中央部分に配される無機質繊維材と、パネル幅方向端部に配置される無機質材で構成し、特に無機質繊維材の繊維方向をパネル厚さ方向に設定した断熱耐火パネルが開示されている。   Further, Patent Document 2 (Japanese Patent No. 2875743) includes an inorganic fiber material arranged at a center portion in the width direction of a panel and an inorganic material arranged at an end portion in the panel width direction as a heat insulating material filled between outer skins. In particular, a heat-insulating fire-resistant panel is disclosed in which the fiber direction of the inorganic fiber material is set in the panel thickness direction.

特公平８−１９７５７号公報。Japanese Patent Publication No. 8-19757. 特許２８７５７４３号公報。Japanese Patent No. 2875743.

前記特許文献２には、断熱材として無機質繊維（ロックウールなど）を表裏外皮間に充填するに際して、パネルの厚さ方向の強度を高めるために、無機質繊維材の繊維方向をパネル厚さ方向に設定することが提案されているが、その製造が煩瑣である。   In Patent Document 2, in order to increase the strength in the thickness direction of the panel when filling inorganic fibers (such as rock wool) as a heat insulating material between the front and back outer skins, the fiber direction of the inorganic fiber material is set in the panel thickness direction. It has been proposed to set, but its manufacture is cumbersome.

即ち一定繊維方向で固化されているロックウール板を、パネルの厚みに対応して一旦短冊状に切断し、更に短冊状の複数のロックウール板片を、所定方向に変換して外皮間に隙間無く充填することになり、その製造装置が非常に煩雑な構成となる。   That is, the rock wool plate solidified in a certain fiber direction is once cut into strips corresponding to the thickness of the panel, and a plurality of strip-shaped rock wool plate pieces are converted into a predetermined direction to form gaps between the outer skins. The filling apparatus is filled without any problems, and the manufacturing apparatus becomes very complicated.

そこで本発明は、芯材にロックウールを採用して耐火能力に優れたものとし、且つその製造が容易である新規な断熱耐火パネルを提案したものである。   Accordingly, the present invention proposes a novel heat-insulating fire-resistant panel that employs rock wool as a core material and has excellent fire-proof capability and is easy to manufacture.

本発明に係る断熱耐火パネルは、金属板で形成される表裏の外皮間に、適宜な断熱部を充填したサンドイッチ構造の断熱耐火パネルにおいて、断熱部における端面形成部以外の充填物（芯材）を、繊維方向が一定方向に配列されていない鉱物繊維体としてなることを特徴とするものである。又特に前記鉱物繊維体が、結合剤と共に鉱物繊維を圧縮した繊維層を、更に繊維層長手方向に圧縮して繊維層を波状とした後所定の加熱処理をして板状に形成したものである。   The heat insulation fireproof panel according to the present invention is a sandwich heat insulation fireproof panel in which an appropriate heat insulation portion is filled between the outer and outer skins formed of a metal plate, and a filler (core material) other than the end face forming portion in the heat insulation portion. Is a mineral fiber body in which the fiber direction is not arranged in a fixed direction. In particular, the mineral fiber body is formed into a plate shape by compressing the fiber layer in which the mineral fiber is compressed together with the binder, further compressing the fiber layer in the longitudinal direction to make the fiber layer corrugated, and then performing a predetermined heat treatment. is there.

従って断熱部を組み込む際に繊維方向をパネル厚さ方向に揃える必要が無く、板状のまま使用しても、パネル厚さ方向において充分な圧縮強度を確保できるものである。   Therefore, it is not necessary to align the fiber direction in the panel thickness direction when incorporating the heat insulating portion, and even when used in the form of a plate, a sufficient compressive strength can be secured in the panel thickness direction.

また本発明（請求項３）は、断熱部の端面形成部が、石膏ボード又はマグネシア系発泡体で構成されると共に、一方の端縁に連結接続時に圧縮されるクッション機能を有する無機質材からなる目地部で形成してなるもので、パネル連結接続部分に断熱部未充填部分が生じないので、断熱機能が充分に確保される。   Moreover, this invention (Claim 3) consists of an inorganic material which has the cushion function compressed at the time of connection connection to one edge while the end surface formation part of a heat insulation part is comprised with a gypsum board or a magnesia type foam. It is formed by the joint part, and the heat insulating function is sufficiently ensured since the heat insulating part unfilled part does not occur in the panel connecting and connecting part.

本発明の構成は上記の通りであり、板状の芯材の端面に所定の処理を施し（端縁形成部を接着する）、心材の表裏に金属製外皮を貼着するのみで製出できるもので、製造の簡素化を実現する断熱耐火パネルを提供できたものである。 The configuration of the present invention is as described above, and it can be produced simply by applying a predetermined treatment to the end face of the plate-like core material (adhering the edge forming portion) and sticking the metal outer skin to the front and back of the core material. Therefore, it was possible to provide a heat-insulating and fire-resistant panel that achieves simplified manufacturing.

図は本発明の実施形態を示したもので、その基本的構成は、パネルの表裏に配される金属板で形成される外皮１と、表裏の外皮１間に充填配置される断熱部２で構成されるサンドイッチ構造で、端縁（パネル幅方向端部）に前記外皮１と断熱部２で形成される連結部３を設けたものである。   The figure shows an embodiment of the present invention, and the basic configuration thereof is an outer skin 1 formed of a metal plate arranged on the front and back of a panel, and a heat insulating portion 2 filled between the outer and outer skins 1. In the sandwich structure configured, a connecting portion 3 formed by the outer skin 1 and the heat insulating portion 2 is provided at an end edge (an end portion in the panel width direction).

断熱部２は、芯材２１と、端縁形成部を構成する端縁ボード部２２及び目地部２３からなり、芯材２１は板状鉱物繊維体（ロックウールボード）で形成され、端縁ボード部２２は石膏ボード又はマグネシア系発泡体で形成され、目地部２３は目地機能（適宜なクッション性）を備えたセラミックファイバーブランケット又はロックウール等で形成される。   The heat insulating part 2 includes a core material 21, an edge board part 22 and a joint part 23 constituting an edge forming part, and the core material 21 is formed of a plate-like mineral fiber body (rock wool board). The portion 22 is formed of a gypsum board or a magnesia-based foam, and the joint portion 23 is formed of a ceramic fiber blanket or rock wool having a joint function (appropriate cushioning property).

特に芯材２１に採用する板状鉱物繊維体は、結合剤と共に鉱物繊維を圧縮した繊維層を、更に繊維層長手方向に圧縮して繊維層を波状にし、所定の加熱処理をして板状に形成したものである。   In particular, the plate-like mineral fiber body adopted for the core material 21 is a plate-like fiber layer obtained by compressing a fiber layer compressed with mineral fibers together with a binder, further compressing the fiber layer in the longitudinal direction of the fiber layer, and performing a predetermined heat treatment. Is formed.

従って特に繊維方向をパネル厚さ方向に揃える必要が無く、板状のまま使用しても、パネル厚さ方向において充分な圧縮強度を確保でき、間仕切り壁として充分な機能を発揮できるもので、そのパネル製造は、前記板状の芯材２１のパネル幅方向の端面に、後述するとおりに端縁ボード部２２と目地部２３を貼着し、前記断熱部の表裏に後述する連結部３を形成するために所定の形状に折曲加工した外皮１を貼着するのみで、断熱耐火パネルが製出できるものである。   Therefore, it is not particularly necessary to align the fiber direction in the panel thickness direction, and even if it is used in the form of a plate, sufficient compressive strength can be secured in the panel thickness direction, and a sufficient function as a partition wall can be exhibited. Panel manufacture sticks the edge board part 22 and the joint part 23 to the panel width direction end surface of the said plate-shaped core material 21 so that it may mention later, and forms the connection part 3 mentioned later on the front and back of the said heat insulation part. In order to do so, it is possible to produce a heat-insulating and fire-resistant panel simply by sticking the outer skin 1 bent into a predetermined shape.

次に外皮１の折曲加工と端縁形成部（端縁ボード部２２と目地部２３）で形成される連結部３について説明する。連結部３は、一方の端縁に設けた嵌合凹部３１及び差込突部３２と、他方の端縁に設けた嵌合突部３３及び差込受け部３４とを備えてなるにものである。   Next, the connecting portion 3 formed by bending the outer skin 1 and the edge forming portion (the edge board portion 22 and the joint portion 23) will be described. The connecting portion 3 includes a fitting recess 31 and an insertion protrusion 32 provided at one end edge, and a fitting protrusion 33 and an insertion receiving portion 34 provided at the other edge. is there.

嵌合凹部３１は、表裏外皮１をパネル幅方向において、パネルの嵌合部分の幅方向距離に基づいて適宜定められる断熱部２の端縁ボード部２２の位置まで内側に折り返して（折返部１１）形成したものである。   The fitting recess 31 folds the front and back outer skins 1 inward in the panel width direction to the position of the edge board portion 22 of the heat insulating portion 2 that is appropriately determined based on the width direction distance of the fitting portion of the panel (the folding portion 11). ) Formed.

差込突部３２は、前記折返部１１の断熱部端縁位置で厚さ方向中心に向って折曲し（当接部１２）、更に端縁方向に突出して膨らみを持たせて折り返し、適宜な弾力性を備えるように設けたものである。   The insertion protrusion 32 is bent toward the center of the thickness direction at the edge position of the heat insulating portion of the folded portion 11 (abutment portion 12), and further protrudes in the edge direction so as to have a bulge, and is appropriately folded. It is provided with a good elasticity.

他方端縁の嵌合突部３３は、外皮１の端縁側部分を、前記嵌合凹部３１内に挿着する分だけパネル厚さ方向においてその厚さを少なくなるように折曲し、且つ前記嵌合凹部３１と対応する幅方向長さ位置において、厚さ方向中心に折曲して設けたものである。   The other end fitting projection 33 is bent so that the edge side portion of the outer skin 1 is reduced in the panel thickness direction by the amount inserted into the fitting recess 31, and In the width direction length position corresponding to the fitting recessed part 31, it bends and is provided in the thickness direction center.

差込受け部３４は、嵌合突部３３の先端面１３において、差込突部３２と対応する位置で、外皮１を幅方向奥方に折曲し、更に外方に折り返してＵ状部１４とし、そのＵ状部１４内に形成したものである。   The insertion receiving portion 34 bends the outer skin 1 in the depth direction in the width direction at a position corresponding to the insertion protrusion 32 on the distal end surface 13 of the fitting protrusion 33, and further folds outward to return the U-shaped portion 14. And formed in the U-shaped portion 14.

また表裏両側に設けた前記Ｕ状部１４の間に、目地部２３を先端面１３より幅方向外方に突出して配置し、目地部２３の背後に端縁ボード部２２を配置し、両端の端縁ボード部の間は、芯材２１が充填されているものである。   Further, between the U-shaped portions 14 provided on the front and back sides, a joint portion 23 is disposed so as to protrude outward in the width direction from the front end surface 13, and an edge board portion 22 is disposed behind the joint portion 23. Between the edge board portions, the core material 21 is filled.

而して建物内の所望位置の天井及び床面に設けた保持レール部で前記パネルを起立保持させると共に、パネルを連結して間仕切り壁を構築するもので、連続するパネルは、図２に例示するとおり、嵌合凹部３１に嵌合突部３３が嵌合すると共に、差込突部３２が差込受け部３４に圧入されて連結されるものである。   Thus, the panel is erected and held by holding rail portions provided on the ceiling and floor surface at desired positions in the building, and the partition wall is constructed by connecting the panels. The continuous panel is illustrated in FIG. As shown, the fitting protrusion 33 is fitted into the fitting recess 31, and the insertion protrusion 32 is press-fitted into and connected to the insertion receiving part 34.

従って連結されるパネルは二重嵌合となり、且つパネル厚さ方向に適宜な弾性を備えた差込突部３２を差込受け部３４内に挿入するものであるから、当該弾性による反発力で、更に強いパネル連結が実現する。   Therefore, since the panels to be connected are double-fitted and the insertion protrusion 32 having appropriate elasticity in the panel thickness direction is inserted into the insertion receiving portion 34, the repulsive force due to the elasticity is used. A stronger panel connection is realized.

また外皮１の嵌合（噛み合わせ）が二重になるので、図３に例示するように、火災時に接着剤が高温で炭化し、外皮１が熱膨張して断熱材と分離し湾曲膨出状態に至っても、差込突部３２と差込受け部３４の連結が維持され、外皮１同士が分離せず一体連結が維持されるので、優れた耐火能力を備えることになる。   Since the outer shell 1 is fitted (engaged) twice, as illustrated in FIG. 3, the adhesive is carbonized at a high temperature in the event of a fire, and the outer shell 1 is thermally expanded and separated from the heat insulating material, so that the curved bulge is generated. Even if it reaches a state, since the connection of the insertion protrusion 32 and the insertion receiving part 34 is maintained, and the outer skins 1 are not separated from each other, the integrated connection is maintained, so that an excellent fire resistance is provided.
